What are the surface treatments of gabion net

Plastic covered gabion net is a net box made of hexagonal net (hexagonal net) woven by one-way twisting and twisting metal wires for two weeks by machine. It is also called gabion and pad with a thickness of 0.15-0.5m (including 0.5m). Gabion net pad is divided into several cells by diaphragm. In order to strengthen the structural strength of gabion net pad, steel wires with larger diameter are selected at the edges and ends of all panels.

Gabion mesh pad is divided into two categories: Plastic gabion mesh metal coating and PVC / PE coating. The metal wire diameter used is different according to the size of the hexagon. The production process is to make Gabions and pads after weaving, cutting, locking and binding. Gabions and pads are supplied in folded condition.

Basic parameters:

(1) Aperture: 60 * 80mm, 80 * 100mm, 80 * 120mm, 100 * 120mm, 120 * 150mm

The length of some double stranded wires shall not be less than 50mm to ensure that the metal coating and PVC coating of some stranded wires are not damaged.

(2) Wire diameter: there are three wire diameters for gabion mesh - mesh wire, edge wire and binding wire

1. The size of mesh is 2mm-4mm

2. The edge wire is usually larger than the mesh wire, with a thickness of 0.5mm-1mm

3. The binding wire is usually smaller than the mesh wire, most of which are 2.2mm

(3) Steel wire tension: not less than that of plastic coated gabion mesh

(4) Surface treatment 1. Electro galvanizing. The maximum zinc content is 10g / m2. Poor corrosion resistance

2. Hot dip galvanizing. The maximum amount of zinc can reach 300g / m2. Strong corrosion resistance

3. Golfan (zinc aluminum alloy). This is divided into two raw materials, Zinc-5% aluminum mixed rare earth alloy steel wire and zinc-10% aluminum mixed rare earth alloy steel wire. Super corrosion resistance

4. PVC plastic coating. The thickness of plastic wrapping is usually 1.0mm, for example, 2.7mm, and 3.7mm after wrapping. Strong corrosion resistance

(5) Interval: add an interval per meter in the long direction of the gabion net

(6) Scale: customizable

(7) Size of plastic covered gabion net compared with pore diameter and wire diameter
